Answer:
46
Step-by-step explanation:
Let 
represent a number with 
in the ten's position and 
is the one's position.
This means actually has value of 
.
We are given the sum of those digits of is 10; this means 
.
It says if 18 is added to the number , then the result is 
.
So has value and
has value 
.
We are given then:
Subtract 
on both sides:
Simplify:
Subtract on both sides:
Divide both sides by 9:
Rearrange by commutative property:
So the system of equations we want to solve is:
-------------------------Add equations together (this will eliminate the variable and allow you to go ahead and solve for :
Divide both sides by 2:
Simplify:
If and , then 
. since 4+6=10.
So the original number is (46).
18 more than 46 is 18+46=(64) which is what we wanted.
We also have the sum of 4 and 6 is 10 as well.
Yes because without a y-intercept it goes through 0. and can you explain the next part?

EXPLANATION
We want to find the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4).
The point-slope form is given by;
where
is the slope of the line.
If
The point-slope form is
On the other hand, if
Then the point-slope form is,
These two equations are the same when simplified.
Answer:
the standard form is : -2x²+16x -31
Step-by-step explanation:
hello :
-2(x-4)²+1 = -2(x²-8x+16)+1 = -2x²+16x-32+1
-2(x-4)²+1 =-2x²+16x -31
